- 1建築物密集的（地區）。都市計畫也說「建成區」。
A built-up area is a place that has already been covered with houses, shops, roads and other buildings, so there is little open land left — not fields, not forest. You hear this a lot in British English, on the news and on road signs: “You are entering a built-up area” often means “slow down; people live here.” Americans say the same idea with words like urban or developed, though they use built-up too. Keep the when the words sit in front of a noun: a built-up area. Though actually, the same spelling can also describe something that has piled up (built-up dirt on a window); that is a different use. Here we mean land that has been filled with buildings.
這個字指已經蓋滿房子、商店、道路和其他建築，幾乎沒有空地留下來的地方，不是田野，也不是森林。英式英文裡很常聽到，新聞或路標上會寫「You are entering a built-up area」，意思通常是「慢下來，這裡有人住」。美式英文也用類似的概念，常換成城市的或已開發的說法，但也會用 built-up。放在名詞前面時要保留連字號，像「a built-up area」。
同樣的拼法也可以指東西堆積起來，例如窗戶上積了一層髒污，那是另一種用法，這裡講的是土地被建築填滿。
組成built (the past of build) + up: buildings have been put up until the land is full of them.
